NOV. 11, 1930. A KOEPSELL 1,781,331 I GR ATE Filed June 1. 1929 gwwwltoz :Patented Nov. 11, 1930 mm; KOEPSELL, or MA VILIJE, isconsin 1 Application filed June 1,

' This invention relates to improvements in 1 stove grate shaking mechanism and pertains particularly toa device whereby oscillating grate units maybe'given various degrees of 1 oscillatory movement The invention broadly contemplates the provision of a structure formed to receive 1;

the projecting polygonal, shaped ends of a plurality of oscillatory grate bars. These projecting ends of the bars are engaged by an operating crank having a guide lug thereon. The projecting ends of the grate bars 1 are received in the structure through aligned apertures in a seriesof spaced plates, each 1 of these apertureshaving ofi -set portions, the

oii-set of one aperture being in alignment Iwith the oft-setof the next or other aperture, Stop members extend between the plates and 1 limit the oscillatory movement 0f the crank 1 by obstructing the movement of the lug carried thereby; stop members various degrees of oscillat on 1 of the grate bars are permitted by shifting the cranklongitudinally of the gratebar to 1 move the lug through the different apertured plates.

1 aconsideration the following detailed description taken in connection withthe accomno material departure from the salient tea .as expressed in the tures of the invention, vappended claims. 1 t In the drawing eetheqline l-Q-l of Figure 2; 11 1 By thearrangement of the;

Referring to the drawing wherein like numerals of reference indicate corresponding parts throughout the several views, the numeral 1 indicates generally the lower portion ot a furnace casing showing applied thereto the structureembodying this invention which structure is indicated by thenumeral 2 and is formed to receive, as hereinafter described, the projecting polygonal shaped ends 3 of the furnace 1 oscillating grate members 4. 1 1 1 1 1 The structure comprises an elongated ens- 1 ing 5 having the front wall 6, end walls 7 and a removableback wall 8. The end walls 7 and the top and bottom walls 9 are provided with a flange 10 and that portion of the casing lying between the flange and the 1 1 1 1 removableback wall1 is adapted to extend 1 11 The invention will be best understood from through a suitableuopening formed in the furnace body 1 so asi-to bring the flange l0 thereagainst to be secured thereto in the manner shown. a 1 1 r r 1 1 Thedront andbackwvalls 6 and 8 respec- 1 tivelyz are provided with suitable aligned apof ashaking or crank handle 13. 1 Figure 1 1s a vertical view in front elevation of the structure; embodying the present; 1 invention showing the same in position in a 1 furnace, the structurebeing sectioned upon 9 ertures to receive the polygonal shaped extensions 3 projecting from the forward end of each of the grates 4, the apertures of the for- 1 ward wall of the device being of materially greater diameter than' the extensions 3, as indicated at 11 so as to permit of the extension 1 therethroughof the enlarged socketed end 12 As shown in Figure 1 each of the apertures 11 ha'sa lateral recess 14 opening therefrom to permit of the passage ofa lug 15 carried upon the forward end of the crank. 1

Interposedl between the front and back a shaker handle adapted for engagement With each extension and having a lug designed to move between the stops of either of said pair for the control of the oscillatory motion of the grate to Which the handle is connected.
